About telemetry, and ads: It is also present in MacOS, but less invasive indeed. And about not showing something down my throat: the other day my iphone just told me in declarative, with a single accept button: now your system will be updated to ios27 (download of updates was enabled, with manual confirmation).
Also having to unlock every app after every brew update in the applications as they "have been downloaded from the internet"... it is not something i'd call refreshing and not working against me.
